June 1855- Nakodadi, Japan a small bear-like cub shot by Mr Wright, was the only mammals and birds obtained at this Port. Several "Cryotes" were seen in the meadows back of the town, where their holes were quite numerous, but none were shot. 12th In the middle of Nakodadi Bay, there is an extensive area of shelly and gravelly bottom in from 8 to 14 fathoms, which is thickly covered with large Holothurians and Echini, and affords a fine field for the researches of the marine Zoologist. My attention was first called to this ground by observing numbers of fishing boats collected there, which I found on approaching them, to be engaged in dredging for Shells and Echinoderms, which are here used as food. The dredge used by these fishermen resembles our zoological dredge except that the frame is made of wood, and sunk by a heavy attached stone. This is dropped at the desired spot, the boat then being moved off to a considerable distance - the length of the dredge-worms - and anchored by the boom, the dredge is thus hauled in on the opposite side. June 1855- Nakodadi, Japan Finding this spot very prolific in new and rare forms of invertebrate I spent several days in dredging it. Radiata were particularly abundant, including three Ophiura, two Eolaster (corresponding to our S. japponica and S. endeca) as large Uraster like our rubens, an Astro-pseetus. Several Holothurians two of which belonged to the genus Pentacta, one being the P. fimosa before mentioned. Of Crustacea a dozen species of Amphipods were found, and half that number of shrimps; also a Dorippe. The dredge also brought up two Coniim fishes, a Liparis and a Hippocampus. 13th This day I continued my examination of the ground noticed yesterday. In the afternoon as my general custom now is, I visited the town. 14th This morning I visited a curious cave in the rocky bluffs forming the eastern cape of Nakodadi Bay. In this cave Mr Squires of the "Hancock" had recently obtained some bats, and I wished to secure some specimens myself. It is accessible only by boat, and extends some hundred yards into the solid rock, with high arched roof and great depths of water. Having made
